I've got a photo of a painting that has an irregularly shaped glare reflection. I've been getting decent results using the Free Select tool and mild stages of brightness/contrast reduction on progressively smaller areas of the image to avoid an obvious border where the filter has been applied but wondering if there's a better, quicker more effective way to do it. 

Thanks!

Hi, I am trying to create my own PBR textures for Blender. The below link says a lot of things about it ( some of them I do not understand )

https://docs.ambientcg.com/books/creating-pbr-materials

In short, a PBR texture inputs colour, roughness, displacement and normal PNGs or JPGs as seen below



Wondering whether I can create them using GIMP?

I took a photo on my mobile of a wooden material and applied it as colour, which works. Then I tried roughness and displacement. Roughness using grey scale + Bump map in GIMP and displacement using filter > map > displace.

Both roughness and displacement JPG worked but with little detail added. I guess, my base photo is not very rich in detail (maybe I am wrong because I used a 108MP camera ).

It would be nice to know if such actions can be performed using GIMP.

Commiserations to France for coming so close. Apparently the French were well behaved due to the weather and because they are well behaved.

Starting with a .jpg taken by a cousin with an iPhone of a painting done by a relative. 

Properties of the original .jpg I was sent per Gimp are: 

42" x 56" 
72 ppi
3.7 mb
RGB

It's a pic in sharp focus of the painting in a frame. The plan is to crop out just the painting, straighten it and bring it down to the original size of 23.5" x 29.25" and have it printed with some border around it for framing.

What do you recommend as the optimal workflow to go from the original to a format to have a print made of it and what method of printing do you recommend? Office Depot does prints that size as posters but they use a variety of inkjet printer and I wonder if there's something better that an actual print shop might use. The goal is to retain as much of the sharpness and detail as possible.

What DPI should I use for best results? I gather most places like .pdf as a file to print from? Is there a particular stock you recommend?

Thanks!

Hello people
it is possible to show Tip of the day after each start of gimp?

Out of curiosity, I made a graph to see the effect of the "blending function" in a gradient, and how it behaves if the midpoint is changed.

I seem to have lost  drawing toolbar.
How can I recover it?

This is in 2.10.18.
Since this version was installed. Some functions are behaving unexpectedly.
At the moment I am looking at "Pencil" and it occupies the whole screen.
How can I reduce it?

TIA

Hello,
For months now various tools and functions have not been working properly or at all in Gimp. The select by colour often makes a selection, but, for example, I can't invert it and delete or change the background, or the selection itself. Once I've made a selection by colour, I have tried the manual command as well as clicking the option in the EDIT tab to fill with forground colour, but nothing happens. There are other tools and functions not working either. I'm stuck. Can anyone help? I have Gimp GIMP 2.10.32 currently. I use a Mac Monteray. 12.6.1

I see the measure tool defaults to pixels, I don't find a setting to change that to any other unit of measure. Is there such a setting and if so how do I access it?

Thanks.
